Fe karbonáty z historického Fe ložiska Poniky-Holý vrch

Polák, Ľuboš, 1989- Fe karbonáty z historického Fe ložiska Poniky-Holý vrch / Ľuboš Polák. -- An interesting Fe mineralization is bound to greywacke, arkosic sandstone and quartz porphyres of the Permian Brusno formation (the Ľubietová Zone of North Veporicum Unit), at the Poniky-Holý vrch near Povrazník village. The Fe carbonates was studied by EMPA and average crystalochemical formula is (Ca0.02Mg0.09Mn0.14Fe0.75)Σ1.00CO3. The chemical composition of siderite from Poniky-Holý vrch deposit is similar to the other hydrothermal mineralization in the Tatricum and Veporicum Unit, however in our case enters to siderite in some cases a higher quantity of Mn – up to 16.73 wt. %. Except of siderite within primary mineralization at the deposit are also quartz and hematite (its variety specularite), from sulphide minerals are present chalcopyrite, pyrite and marcasite. The oxidation zone is represents by goethite, limonite, more unidentified Mn oxides and Fe oxi-hydroxides (lepidocrocite?). From accessories of rocks are present mainly zircon and rutile.
